Police: Suicidal suspect killed San Diego officer

Henwood was the second San Diego officer to be killed while on duty in the last ten months. In July, three people were charged with murder in connection with an October 2010 shootout that killed Officer Christopher Wilson, a 17-year department veteran, and two others. The 50-year-old father of two was the first San Diego officer to be killed in the line of duty in more than six years.

"This tragedy is another grim reminder that our police officers put their lives on the line every day to protect our community, and we are grateful for their courage and sacrifice," San Diego mayor Jerry Sanders said in a statement Sunday.

In the earlier shooting at the restaurant in El Cajon, Martin Hanna was sitting with his girlfriend in his vehicle in the parking lot when he was approached by a man carrying a shotgun, police said. The man shot Hanna in the face with a single round before he fled in an Audi, they said.

Investigators had not established any relationship between White and Hanna, who was expected to survive.

Minutes later, an officer with no knowledge of that shooting spotted the Audi speeding and gave chase but abandoned the pursuit as it reached speeds of 100 mph. The attack on Henwood came shortly after that.
